Perhaps I should admit on the title page that this book is "By L. Frank Baum and his correspondents," for I have used many suggestions conveyed to me in letters from children. Once on a time I really imagined myself "an author of fairy tales," but now I am merely an editor or private secretary for a host of youngsters whose ideas I am requestsed to weave into the thread of my stories.  
These ideas are often clever. They are also logical and interesting. So I have used them whenever I could find an opportunity, and it is but just that I acknowledge my indebtedness to my little friends.
 
My, what imaginations these children have developed! Sometimes I am fairly astounded by their daring and genius. There will be no lack of fairy-tale authors in the future, I am sure. My readers have told me what to do with Dorothy, and Aunt Em and Uncle Henry, and I have obeyed their mandates. They have also given me a variety of subjects to write about in the future: enough, in fact, to keep me busy for some time. I am very proud of this alliance. Children love these stories because children have helped to create them. My readers know what they want and realize that I try to please them. The result is very satisfactory to the publishers, to me, and (I am quite sure) to the children.
 
I hope, my dears, it will be a long time before we are obliged to dissolve partnership.
 
L. FRANK BAUM.
